h century, Dr. Petrie, in his relative note,
adds--"but now considers as of the tenth, or perhaps eleventh."

To the paper on "Leprosy and Leper Hospitals in Scotland and England" is
now added a series of additional "Historical Notices," prepared by Dr.
Joseph Robertson, with the accuracy and research for which, as is well
known, my early friend was conspicuous.

The origin of the tract on "Medical Officers in the Roman Army" is
explained in the following note, prefixed to the first edition:--"A few
years ago my late colleague, Sir George Ballingall, asked me--'Was the
Roman Army provided with Medical Officers?' He was interested in the
subject as Professor of Military Surgery, and told me that he had made,
quite unsuccessfully, inquiries on the matter in various quarters, and
at various persons. I drew up for him a few remarks, which were
privately printed and circulated among his class at the time. The
present essay consists of an extension of these remarks."

The essay on the monument called "THE CATSTANE" suggested an
explanation, which naturally elicited divergent criticisms. Some of
these appear to have occasionally engaged Sir James Simpson's attention;
and from some unfinished notes among his papers, it seems plain that he
meant to notice them in an additional communication to the Society of
Antiquaries.

In these notes, after recapitulating at the outset the facts adduced in
his first paper, Sir James proceeds:--"These points of evidence, I
ventured to conclude, '_tend at least to render it probable_' that the
Catstane is a monument to Vetta, the grandfather of Hengist and Horsa.
But I did not consider the question as a settled question. I began and
ended my paper by discussing this early Saxon origin of the monument as
problematical and probable, but not fixed. At the same time, I may
perhaps take the liberty of remarking, that both in archaeology and
history we look upon some questions as sufficiently fixed and settled,
regarding which we have less inferential and direct proof than we have
respecting this solution of the enigma respecting the Catstane. The
idea, however, that it was possible for a monument to a historic Saxon
leader to be found in Scotland of a date antecedent to the advent of
Hengist and Horsa to the shores of Kent, was a notion so repugnant to
many minds, that, very naturally, various arguments have been adduced
against it, while some high authorities have declared in favour of it.
